Smart Board Activity – Using a Venn Diagram to classify the states of matter and the changing phases. The purpose of this activity was to visually represent how the states of matter and the phase changes are related to each other.
I pulled up the Venn diagram onto the Smart Board screen with the list of words and phrases listed on the right side. This Venn diagram has circles/categories for solid, liquid, and gas. I reminded the students that wherever the circles overlap, it is something that both categories had to have in common, or it was a true statement for both. Where all 3 circles overlap, it is something that all 3 categories must have in common.
I divided the class into small groups. I explained that each group would have a turn at the Smart Board, sending one person at a time as their representative. In their small groups, the students discussed amongst themselves what words or phrases they would like to place into the Venn diagram. They also had to decide who would go first, and so forth. I set this activity up to be a friendly competition to see which group can get the most items placed into the Venn diagram correctly.
Using the tri-fold brochure for their note taking, they took notes in blue or red colored pencil. They used the blue colored pencil for the phrases that were in blue and related to the properties for each state of matter, red for the words that were in red and referred to each of the phase changes. They only wrote down the answers if they were placed correctly into the Venn diagram, I didn’t want them working ahead. This kept their focus on the board. If a student did place a word/phrase into the wrong spot, I moved it back to the list on the right. The next team could either correctly place the word/phrase into the diagram or choose a new word/phrase.
From start to finish, this activity took about 25 minutes. Overall, the activity went really well and the students were engaged and enjoyed the friendly competition.
For HW, students will review the terminology related to phase changes, as well as read about hot water freezing faster than cold water.
